The document discusses three main types of communities: rural, urban, and tribal. It provides characteristics of each:
Rural communities are based in villages and dependent on agriculture. They have low population densities, intimate social relationships, and oral traditions. Agriculture is the main occupation.
Urban communities include towns and cities with higher population densities, non-agricultural occupations in industries like trade, manufacturing, and services. They have greater social mobility and heterogeneity.
Tribal communities live in isolated forest or hill areas, have a distinct culture and language, and are united under a chief. They have strong ethnic identities and are economically self-sufficient through practices like barter exchange.
